To aZZ whom it vita/y concern:

Be it known that 1, WILLIAM F. .MCNARY,

ments in Plumbers Shave-Hooks, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming a part hereof.

This-invention relates to plur'nbers shavehooks; and it consists of the novel construchereinafter-shown, described, and claimed.

The object of this invention is to provide an improved share hoolghaving a gage attachment, whereby it is rendered possible to width.

' Figure lis e perspective view showing thy complete invention. Fig. 2 is a view showing the device in position for use. Fig. 3 isaperspective view of a. portion of a pipe which has been operated upon'by my improved shavehoolr. r

In the construction of my invention I provide a, handle 1,' attached to a rod 2, on the opposite end of which is the scraper 3, which, as shown, is substantially triangular in form and which is provided with cutting edges enof the rod 2 is a graduated scale 4, and the other side of said rod is provided withe series of openings 5, arranged at suitable distances from each other. 1

.6 indicates a gage-disk mounted upon the rod 2 andifprovided on one side with a. projecting hiib or sleeve 7, having an opening in which is mounted a. set-screw 8. The disk 6 may be operated upon the rod 2, and by referring to the scale at the operator can determine the exact width of the surface operated upon. When the disk 6 is placed in the desired position, the set-screw S is operated, its inner end engagi n g withinthe openings 5,and thereby holding it securely in position. The.

gdisk, and a projecting hub integral with the Serialllo. 53,515. (No model-3' and thereby hold the'disk 6 rigid on the rod 2, even though the set-screw become loose within the opening. The advantage of this arrangement may readily be seen, for were the set-screw engaged only against the face of the rod-the disk would slide upon the rod whenever the set-screw became loose. This inconvenience is avoided by arranging the openings as described. The disk 6 is'of such diameter that in projects farther away from the rod 2 than does the scraper 3, so that when the said scraper 3 is operated upon a pipe or other surface the said disk will bear against the end or side of the body which is operated upon. By this means the scraper 3 may be operated over a. surface of uniform width and the gage can be made to operate over a greater or less surfnbe as desired.

I I claixn- 1 I The combination in a shave-h0ok,of a square.

rod having agreduated scale formed on one side so that the space to be operated upon can be measured and a series of depressions formed at equal intervals on another side thereof, aiscrsper removablyconnected to one end of the rod, a gage-disk rhounted to slide upon said rod,.and extending equal distances from all sides thereof so that any side of the scraper can be used without changing the rearside of said disk and having an opening formed therein and a set screw extending through the said openingand adapted to engagein the depressions formed in the rod and thereby holdthe disk stationary upon the' rod,

substantially as specified. i

In testimony whereof I afiix my signature in presence of two witnesses.
